Continuous property, it is believed that do not patrol path and be classified into several segmentations for having certain length, such as lε1And lε2.With lε1For, system is from line attendant
In the historical data for uploading latitude and longitude coordinates, meeting formula d is found outij≥dsupPoint range (a1,b1),(a2,b2),(a3,b3)…(an,
bn) do not patrol the point range of the cut cable as line attendant, in addition, separately adding two o'clock (a from beginning to end0,b0) and (an+1,bn+1) it is used as boundary
Judge a little.There is (a0,b0) and (a1,b1), (an,bn) and (an+1,bn+1) linear equation be：
And have parallel with cut cable and at a distance of dsupLdEquation is：
Joint type (7) and formula (9), formula (8) and formula (9) respectively, can acquire two intersecting point coordinates is (a0.5,b0.5) and
(an+0.5,bn+0.5).Their value is respectively：
The two intersection points are line attendant's non-line walking portion boundary point in actual work.Therefore, the distance of this point-to-point transmission
It is exactly not patrol cable length caused by this deviation cut cable of the line attendant.Distance can pass through formula therebetweenIt acquires.
Fig. 2 is that path of not patrolling of the invention returns calculating schematic diagram.As shown in Figure 2, first have to find line attendant deviate and
Point coordinate (a of line walking maximum distance when returning cut cablei,bi) and (aj,bj), with (ai,bi) for, specific algorithm is：First
By system record in front of and after discontinuous point n point position merging suspicion maximum distance point set P.The value of n depends on line attendant and exists
One back gauge d of cut cablesupWithin change nyctitropic number, take under normal circumstances n be line attendant deviate cut cable when final stage
Coordinate points quantity on dull path.
The point being placed in P at this time is (ai-1,bi-1) and (ai,bi).In order to seek out most distant point when line walking, connect
The projected length got off by this two o'clock on cut cable：
Wherein, xi-1As projected length；And di-1And diRespectively (ai-1,bi-1) and (ai,bi) arrive institute's inspection cut cable
Distance.
It is d since inspector's maximum can inspect rangesup, therefore when by being located at these to inspector on cut cable
Accessible inspection range is compared, and just can obtain most distant point：
IfThen illustrate (ai,bi) it is most distant point, otherwise then indicate (ai-1,
bi-1) it is most distant point.When there is n element (a in P1,b1),(a2,b2),(a3,b3)…(ai,bi) up-to-date style (13) becomes：
Thus the most distant point that just can obtain line attendant both sides after deviateing and returning cut cable, accordingly again to the two
Point judges effective line walking distance of the cut cable, and can acquire whether it cover cut cable does not patrol path, if
It does not cover, and leaves and how much do not patrol path distance.
With (ai,bi) and (aj,bj) for, it can be in the hope of the projector distance x of point-to-point transmission by formula (12)ij, which is original
That originally leaves does not always patrol path length.Then calculate two o'clock covering inspects range：
To inspecting range di,jAnd length x is not patrolledijDifference is sought, can show that line attendant makes up situation to do not patrol path：
Δ d=xij-di,j (16)
